Yes, that't the idea. Just sharing under one tree, no replication or 
whatever, only one username/login pair for each user (different, of 
course :)

Well, a coleague told me that AFS can do it, so I turned to coda as a 
newer and supposedly better solution.
Now, is AFS better because it can do what I want to, or not?

That's what I had in mind...still not very well with the terminology... :)

Yes, I've put a root server on my machine, and another replica server on 
coleagues machine.
Every replicated volume is nicely propagated from master to slave (so to 
say), and every kind of administration is done exclusively on my 
machine, which is a root server.

Well, we looked for couple of days for such a solution, but couldn't 
find any that is free, opensource etc.
Almost everywhere you have coda or afs coming up as a solution, or some 
p2p solutions, which on the other hand, is not exactly what we had in 
mind...

So, can you tell me (or anybody) what software to use for my needs, or 
at least, how to make coda work the way I want?

We'd appreciate any help....

Thanks, Andrea
